Baloth Frenzy
With the Rampaging Baloths in play, any time you play a land, you activate the Wirewood Savage ability to draw a card, which increases your chance to put a land on top of your library, thus activating the ability of the Oracle of Mul Daya, which causes a loop until you decide to stop it because both cars have the "you may" option in the text.
If you can't lay a land, simply activate Garruk's primary ability to put a beast into play to start the loop.
I made this deck after the pre-release tournament for Zendikar, and it works incredibly well, regardless of the lack of board control.
By turn five, I usually begin a loop of beasts. Even though they have summoning sickness, the Herd Gnarrs still get real big, with trample and rampage abilities due to other beasts on the field. (hopefully)
